Benefits of technology
The present invention is a suspension system for vehicles, specifically a front suspension system for a saddle-riding type vehicle. The system includes a vehicle body frame, a suspension arm, and a shock absorber. The suspension arm has a first end pivotally attached to the vehicle body frame and a second end supporting a wheel. The shock absorber has a first end connected to the side of the vehicle body frame and a second end connected to the suspension arm. The suspension arm includes a first arm member, a second arm member, and a third arm member that are pivotally connected to each other and operatively associated with the vertical movement of the wheel to cause the shock absorber to make a stroke motion. The first and second arm members are disposed so as to form a V-shape. The suspension system can be a double wishbone type suspension for a front wheel in a rear-wheel-drive all-terrain vehicle (ATV). The invention aims to enhance the degree of freedom in layout and in setting the stroke ratio by minimizing the increase in the number of parts used and weight of the suspension system.
Problems solved by technology
On the other hand, having the linkage mechanism separately from the suspension arm tends increase both the number of component parts used and the weight, and to impose restrictions on a degree of freedom in layout.
In addition, the suspension arm is formed from a single member, which makes it difficult to tune the stroke ratio.

A vehicle suspension system includes a vertically reciprocally movable suspension arm assembly having a minimal number of component parts and configured to be light in weight. The suspension arm assembly includes a lower arm portion including a plurality of arm members which are operatively connected together via a plurality of hinge joints. The arm members are operatively associated with each other in a manner so as to permit vertical reciprocating movement of a wheel, and are interconnected in a manner so as to permit a shock absorber to make a stroke motion, where one end of the shock absorber is attached to a portion of a vehicle body, and another end of the shock absorber is attached to one of the arm members.
Description
CROSS-REFERENCE TO RELATED APPLICATIONS[0001]The present invention claims priority under 35 USC 119 based on Japanese patent application No. 2009-176360, filed on Jul. 29, 2009. The entire subject matter of this priority document, including specification claims and drawings, is incorporated by reference herein.BACKGROUND AND SUMMARY OF THE INVENTION[0002]1. Technical Field of the Invention[0003]The present invention relates to a suspension system suitable for a relatively small vehicle such as, for example, a saddle-riding type vehicle.[0004]2. Background Art[0005]An arrangement of a suspension system is known for a saddle-type vehicle, including a linkage mechanism disposed between a vertically reciprocally movable suspension arm and a vehicle body, and a shock absorber having one end connected to the linkage mechanism (see, for example, Japanese Laid-Open Patent Document No. Sho 62-61889.[0006]In the known arrangement mentioned above, suspension performance can be improved by vary...
